In the country, the rain would have developed a thousand fresh scents, and every drop would have had its bright association with some beautiful form of growth or life. In the city, it developed only foul stale smells, and was a sickly, lukewarm, dirt-stained, wretched addition to the gutters.Charles Dickens, Little Dorrit (Oxford University Press, 1997; 1855-1857), pp. 30-31.
The rain poured down on London so hard that it seemed that it was dancing spray, every raindrop contending with its fellows for supremacy in the air and waiting to splash down. It was a deluge. The drains and sewers were overflowing, throwing up—regurgitating, as it were—the debris of muck, slime, and filth, the dead dogs, the dead rats, cats, and worse; bringing back up to the world of men all those things that they thought they had left behind them; jostling and gurgling and hurrying toward the overflowing and always hospitable River Thames; bursting its banks, bubbling and churning like some nameless soup boiling in a dreadful cauldron; the river itself gasping like a dying fish. But those in the know always said about the London rain that, try as it might, it would never, ever clean that noisome city, because all it did was show you another layer of dirt. And on this dirty night there were appropriately dirty deeds that not even the rain could wash away.Terry Pratchett, Dodger (London: Doubleday, 2012), pp. 1-2.
